title: [Benzopyrene hydroxylase induction and the functioning of the immunocompetent cells in human peripheral blood].
abstract: Xenobiotics--inducers of benzo(a)pyrene hydroxylase (BPH)--exert different effects on mitogen-stimulated and mitogen-unstimulated human peripheral blood mononuclear cells (PBC). In mitogen-stimulated culture xenobiotics highly increase BPH activity and suppress cell blast transformation. The incubation of the unstimulated PBC in the presence of xenobiotics increases insignificantly BPH activity, intensifies T-cell differentiation and concanavalin A-induced proliferation. The BPH activity is mainly associated with the PBC adhered to plastic Petri dishes. However, the control and induced levels of BPH activity depend on the interaction between adhered and nonadhered cells.
